Letters Patent No. 101,823, dated April 12, 1870.

IMPROVEMENT IN INDIA-RUBBER CARPETING AND EMBOSSED MAT'I'ING.

The Schedule referred to in these Letters Patent and making part of thesame.

To whom it may concern 7 Be it known that 1, JOHN H. Cl-IEEYER, of thecity, county, and State of New York, have invented certain new anduseful Improvements in Vulcanized India-Rubber Carpeting and EmbossedMat-ting, of

which the following is a specification.

My invention relates to carpeting or embossed inatting, composed of alayer of India rubber and a layer of cloth, the India rubber beingplaced on the cloth in a green or plastic state, and, while in suchstate, run between rollers, one of which, that is to say, the

' one in contact with the rubber, is engnved with the design which it isdesired to reproduce in relief upon the rubber.

The rubber, thus combined with 'a backing of cloth, and stamped orembossed, is then vulcanized, so as to produce an ornamented or figuredsheet or strip suitable for carpeting or mat-ting.

In the manufacture of th'is article, it has been usual heretofore toemploy for the cloth backing, a com paratively tine and closely-wovenfabric, which is so thin as not to yield appreciably when compressedbetween the rollers, and, owing to thisunyielding nature of the backing,the rubber has not been' able to properly fill the figures ordepressions in the die or engraved rollers, and, consequently, theembossed or raised figures have had little relief, and have. been butimperfectl y developed or produced upon the matting,

In the course of experiments which I have instituted to remedy thisdefect, I have found that; the diliiculty can be entirely removed byemploying, in lieu of the fabric ordinarily used, a connuonly-calledgnnuy or jute cloth, made of soft and thick strands of jute. Theemploymentof such a cloth not only gives a stronger backing for therubber, but also, owing to the softness and thickness of the strands,ad-

mits of the fabric being compressed to the desired cstent between therolls, so as,to allow the rubber to fill every part of the engravedpoigtions ofthe embossingroll, and causing the figures to be reproducedupon tne rubber,s1u'fitce of the matting with a distinctness andboldness of relief hitherto unattainable, so that not only is thecarpeting made as strong or stronger than heretofore, and with a thickerbody, but the ornamental designs are clearly marked and brought out injust as full relief as the depressions in the embossingroller will admitoi'.'

The employment of the jute also enables me to manufacture. the carpetingor matting at much less expense, and to produce a cheaper and betterarticle than has been before practicable. Again, it is more dumblothanthe ordiuarythin matting-or carpeting, and is not so apt to wear at thepoints where the floor upon which it is laid is uneven.

In carrying out my invention, the same process of manufiicture isemployed as has been in use heretofore, the only difference being that Iemploy the jute or gunny-cloth or canvas in lieu of the canvas or likecloth ordinarily used, so that a further description is not necessary.

Having now described my invention,

What I claim. and desire to secure by Letters ln-tent, is-

As a new mauuihcture, vulcanized 1ndia-rubbercarpeting or embossedmatting, composed of vulcanized India rubber, in combination with abacking of cloth or canvas made of jute, substantially as set forth.

In testimony whereof I. have signed my name to this specific-a tionbefore two 'subscribingwitnesses.
